La Bastide-d'Armagnac

The count of Armagnac, Bernard VI, reached an agreement in 1291 with Arnaud Guillaume de Mauvezin to found a bastide on the latter's land along the river Douze. This area then being within the jurisdiction of Edward I, king-duke of Aquitaine, his senechal, Jean de Grailly, also became involved in fashioning the contrat de pareage and in conferring the important charter of rights and privileges (charte de Coutumesl) five years later.
